i STENCIL CARD FOR USE WITH ADDRESSING MACHINES.

' Application filed August 27, 1924. Serial No. 734,412.

To all whomit may concern:

Be it known that I, LOUIS MAnRion BAR- MAN, a citizen of the United States of America, residing at ltoneo Building, 5,

Holborn, London, E. C. 1, England. Great Britain, have inventednew and useful irrprovement's in Stencil Cards for Use with Addressing ltlachines, of which the following is a specification.

The present invention relates to improve ments in stencil cards for use with address ing machines.

In a former application for Letters Patent Serial No. 605831. filed 9th December 1922 there is described and claimed a combined filing and addressing machine card, the said card being provided with a rectangular opening and a depressed or recessed portion extending inwardly for a. short distance from and surrounding the edges of the opening. The edges of the stencil had secured thereto a. rectangular frame formed preferably from a strong manila paper, the dimensions of the frame coinciding with the recessed portion of the card so that when the stencil. with its frame is secured by an adhesive to the card the surface of the frame is flush with the surface of the card.

This method of securing the stencil to the 30 card is tedious and moreover there is a tendency for the mucilage to spread over the card, or smear the surface.

Furthermore, the recessed portion of the card being only just sufficient in depth to receive the frame it sometimes happens that in affixing a frame to the card part of the frame does not lie within the recess, and in such cases there is a tendency when the stencil card is used in the addressing machine or whenhandling the card in the file, for the overlapping edge of the frame to be barred, and in course of time the thin frame and stencil tears away from its card support.

Now the object of the present invention is to improve upon the method of mounting stencils upon the cards without the aid of a mucilage and in such a manner that burring or tearing away of the stencil from the card support is not possible.

The invention consists in a combined filing and stencil card for addressing machines having a rectangular opening and a depressed or recessed portion surrounding the said opening and a metal frame provided with tangs or projections adapted to secure the stencil to the card, the said metal frame enclosing the recess in the card. a

The invention is applicable to stencils which have been secured to a thin paper frai'ne, or in its preferred form the thin stencil after it has been damped for impression in a typewriter is placed over the opening in the card, the metal frame is then super-imposed and pressure is applied so that the tangs or projections penetrate through the stencil and into the card.

The invention will now be described with reference to the accompanying drawings, whereon Fig. 1 is a plan view of a combined filing and addressing machine card to which the presentinvention is applied.

2 is a cross sectional View of the card shown in Fig. 1.

Fig. 3 is a side view ofthe metal frame provided with the tangs, tongues or pro jections. t

F i g. 4- is a cross sectional view of a stencil aid and stencil frame secured. thereto by means of a metal frame.

Fig 5 is a cross sectional view of a combined filing and addressing machine card having a central opening and recesses on each side adapted to be enclosed by metal frames on each side.

On the drawings 1 shows the combined filing and addressing machine card formed with an opening surrounded by a recessed portion 2, and 3 is the strip of stencil paper which may either be secured to a thin manila frame 4, see Fig. l, or may be placed in the recess 2 over the opening of the card, and be secured to the card by the thin metal frame 5.

The thin metal frame 5 has a central opening 6 of a size substantially that of the opening in the card 1, and is provided with a row or rows of triangular or other shaped, tangs, tongues, or projections 7 around its surface.

In the case of stencils 3 mounted upon thin paper frames 4, after these have been passed through a typewriter to cause the strip of stencilling material to be perforated with a name and address or other matter, the frame 4: with its stencil 3 is placed in the recess 2 of the card 1, so that the stencil paper covers the opening in the card, and the edges of the frame 4.- nest in the recessed portion 2.

(it) i A metal frame is then placed over the frame f and pressure is applied to cause the tangs to penetrate the card 1 and so secure the stencil with its frame to the card. It is to be understood that the tangs do not pass entirely through the card 1 but only penetrate a certain distance into it, which distance is sufficient firmly to secure the stencil and its frame within the recess.

In cases where strips of stencil paper 3 are used without the supporting frames the strip. of stencil after perforation is secured directly in the recess of the card by the metal frame 5.

Best results are achieved by securing the stencil strip to the card under the metal frame while the stencil is in a moist state because when the stencil dries it shrinks and. is held across the opening in the card in a taut condition.

Thus, it is sometimes desirable when. the

perforated stencils have become dry to dampen the strips with water prior to securing them to the cards under the metal frames 5, although good results can he obtained with substantially dry stencils. In Fig. 5 is shown a stencil card 1 having recesses 2 formed on both sides and in this case a thin metal frame 5 is applied to each side of the cardv the stencil strip being secured between the card and the metal frame 5 in one recess on one side while the metal frame is secured direct to the card in the recess on the other side. This method is advantageous where stencil cards are used in power driven addressing machines as the feed rollers of the machine tend to burr over the edges of the card surrounding the opening.

The metal frame, or frames, apart from securing the stencil to the card, stiffen or stiffens the card at its weakest points caused by the opening and. recess or recesses.

Having. thus described my invention what I desire to secure by Letters Patent of the l nited States is as follows 1. A thin metal frame for stencilcards which is engageable with only one face of a stencil, said frame having a central opening and provided. with a plurality of projections capable of penetrating through said stencil and into one surface of a card, and said frame capable of fitting into a recess in the card to engage said stencil directly 1 with the bottom of the recess.

2. A combined filing and stencil card for dressing machines having a rectangular opening and a depressed or recessed portion surrounding the opening, a strip of stencil material, a thin paper frame to which. said stencil strip is secured, and a thin metal frame provided with projections for penetrating said. paper and. strip to secure said paper frame within the confines of said recess.

3. A. combined. filing and. stencil card for addressingmachines as claimed in claim 2-, characterized in that thestrip of stencil paper is perforated and placed over the opening in the card. and nested in the recessed portion, and is secured therein by the metal frame provided With projections which penetrate through the stencil and into the card.

4. A combined filing and stencil card for addressing machines, comprising a card pro-. vided with a rectangular opening and also recesses formed on opposite sides of the card and surrounding said opening, and thin metal frames one of which is mounted in one recess to securea stencil therein and the other being mounted in the opposite recess.

In testimony whereof I have signed my name to this specification.

LOUIS MAURICE BARMAN.
